List two safety measures while thunderstorm.

Explanation

**Step-by-Step Text Solution:**

Vehicles provide a protective environment as they are made of metal, which can help direct lightning strikes away from the occupants.

The metallic body of the vehicle conducts electricity and allows the electric charge from a lightning strike to flow around the exterior and into the ground, keeping the occupants safe inside.
